It will be appreciated that the number of second subslots 12h is less than the number of first subslots 12g, which may allow condensate to be more quickly directed to the atomizing core 11 through the second subslots 12h, while by providing a fourth subslot 12n, a different number of second subslots 12h may be facilitated to communicate with the first subslots 12 g. On the other hand, by reducing the number of the second sub-grooves 12h, for example, providing one second sub-groove 12h, the flow direction of the condensate is facilitated to be controlled.
